Fill your glazed pot with soil. Glazed pots left outdoors without soil or plants are more likely to crack. Use a sterilized potting soil if you intend on planting an ornamental plant inside your glazed pot. Gardeners run the risk of their plant contacting a disease when they use the dirt in their yard. However, unplanted pots may be filled with garden dirt. Create a hole inside of the planter that is large enough for the root ball of the plant. Place the plant inside of the hole and pack soil around the base.
Place your glazed pot on a saucer filled with 1/2 to 1 inch of pear gravel. By preventing your glazed pot from having direct contact with the frozen ground, you prevent moisture from cracking your pot. Use a saucer that is large enough to accommodate the size of the planter. Furthermore, avoid letting water in the saucer touch the bottom of the glazed container. Too much water in the saucer prevents proper drainage, which leads to fungal diseases.
Remove plants and soil from containers that have no drainage holes, as suggested by Front Range Living. Pots with no drainage holes accumulate water at the bottom. Repot any plant growing in the pot. Pick a pot that has drainage holes that are at least 1/2 inch in diameter. Wash out the pot before turning it over to remove dirt and any other types of debris. Turn the pot over to prevent water accumulation.
Reduce the amount of water you give your plant. Any excess water leads to glazed pots cracking. Most plants go into dormancy during the winter months; therefore, they do not need very much water to survive. Avoid cutting off their water too early in the growing season. Also, reduce their water slowly to prevent causing a water-stressed plant. Go back to your normal gardening schedule in the spring when the plant comes out of dormancy.
